SAMUEL E. BOUCHAED, OF BOCHESTER, NEV YORK, ASSIGNOR TO BAUSCH Sa LOMB OPTICAL COll'PliNY, OF RCHESTER, NEW YORK, A CSRPORATTON F NEW' YORK OPHTHALMIC MOUNTING Application filed November 8, 1928. Serial No. 317,988.

This invention relates to ophthalnic mountings and more particularly it has' reference to ophthalmic mountings Which compri se metallic and non-metallic parts in combination. The present invention involves mountings wherein a metallic rim embraces a nonmetallic rim With a lens seated in the nonmetallic rim, similar to the type disclosed in Patent No..1,177,807 issued to F. A. Stevens on March 28, 1916.

One of the objects of the present invention is to proviee an improved ophthalmic mounting having a metallic rim embracing a nonmetallic rim and a lens seated in the non- 3 inetallic rim; another object is to provide such a mounting` with means for holding tonether the non-metallic and metallic rims; and still another object is to provide a mounting of the type described with a non-metallic' rim of such a structure that it Will fit into a metallic rim Which has a more or less standard construction. To these and further ends, the invention resides in certain novelfeatures of construction, arrangement and combination of parts as Will hereinafter be more fully described and pointed out in the appended claims.

Referring to the drawings:

Fig. 1 shows a front elevation of a pair of spectacles embodying my invention.

Fig. 2 shows a top plan View of same.

Fig. 3 is a sectional'view taken on line 3-3 of'Fig. 1.

A preferred embodiment of my invention tallic rim 17 has an outer peripheral ridge or projection 18 and a relatively flat, annular is illustrated in Vthe drawings wherein there' shoulder portion 19 at each side of the projection 18. The inner circumference of the rim 17 is provided with a groove 20 Which receives the edge of a lens 21.

In assemblingl my improved mounting, the :3

non-metallic` rim, Which is preferably a continuous rim Without a split, is forced over the lens 21 so that the lens is firmly seated in groove 20 of the rim 17. The non-metallic rim is yieldable so it can be easily stretched overthe edge of the lens, the proper diameters of rim and lens having, of course, been selected, all as Will be obvious to those skilled 'in the art. The lens, together with its nonmetallic rim, is then inserted in a metallic spectacle frame so that the metallic rim or eye vvire of the frame is clamped around the non-metallic rim tothereby firmly hold the lens.

It Will be noted in Fig. 3 that the peripheral projection 18 of the rim 17 is seated in the groove 15 of the metallic rim 10 and that the shoulder portions 19 of the rim 17 are in abutting' relation With the shoulder portions 16 of the metallic rim 10. Such a structure serves to hold the non-metallic rim Within the meta-llic rim and prevents any twisting or Warping of the rim 17. This is an important feature as it makes it possible to sell the metallic frame with the non-metallic rims mounted therein but Without the lenses, since my improved structure provides a mean-s for securely holding the non-metallic rim Within the metallic rim, even Without clamping the rims around a lens.

The construction of my non-netallic rim is such that it Will properly fit into the groove of a metallic rim Which is more or less standard on the market. v 10, shown in Fig. 3, has a structure Which is relatively common to many metallic frames Which are made and sold.

Besides serving as a shock absorber to reducev breakage of the lens, the non-metallic rim 17 produces an ornamental appearance. Thus, for example, the frame shown in Fig. 1 can be madejwith a black zylonite rim surrounding the lens and with a White gold metallic rim surrounding the black zylonite Thus the metallic rim iea rin thereby producing an efiicct that is pleasing in appearance.

F rom the foregoing' it Will be amp-arent that I am able to attain the objects of my invention and provide an improved ophthalmic mountinp; of the character described. Varions modiiications can obviously be made Without departin from the spirit of the inve'ition as pointed out in the appended claims. lo I claim 1. jin ophthahnc mounting comprising in combination a metallc rim having a groove on its inner circumiterence, a flat, annular shoulder portion on said inner circumference 15 on each side of said groove, a non-metallic rim having' a circun'iferential projection and a fiat.I annular shoulder portion on each side of said projection, said projection beingI seated in said `groove and the shoulder portions on said metallic rim beingv in contact with the shoulder portions on said nonmetallic rim.

An ophthahnic nounting` comprisingI a met-allie rim having; a V-shaped groove on :a inner circumifercmre, a iiat shoulder portion disposed on each side of saidpjroove on said inner circumference, a non-metallic rim having a circinnferential projection and a fiat shoulder portion on each side of said projection7 said lnetallic rim embracing` said nonnetallic rim, With said projection seated in said groove and with the shoulder portions of one rin Contacting With the shoulder portions of the other rim, the annular sides of the two rims being substantially fiush 'With each other.
